The invention relates to the field of electric vehicles and provides a method and device for calculating the cruising range of the electric vehicle. The method for calculating the cruising range of an electric vehicle according to the present invention includes: detecting parameters related to the current available real power of the battery of the electric vehicle, and / or detecting parameters related to the power consumption per unit mileage of the battery of the electric vehicle ; Calculate the current available real power of the battery of the electric vehicle based on parameters related to the current available real power of the battery of the electric vehicle, and / or based on parameters related to the power consumption per unit mileage of the battery of the electric vehicle Calculate the power consumption per unit mileage of the battery of the electric vehicle; calculate the cruising range of the electric vehicle based on the calculated current available real power of the battery of the electric vehicle and / or the calculated power consumption per unit mileage of the battery of the electric vehicle . The invention can make the calculated mileage more accurate.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method and device for calculating the cruising range of an electric vehicle. Background technique [0002] The current calculation method for the cruising range of electric vehicles basically only considers the remaining power of the battery, and calculates the remaining drivable mileage based on the remaining power and the average power usage in the previous period. However, there is a large error between the cruising range calculated by the current electric vehicle cruising range calculation method and the actual mileage that can be supported by the actual electric power of the electric vehicle. SUMMARY OF THE INVENTION [0003] In view of this, the present invention aims to provide a method for calculating the cruising range of an electric vehicle, so as to make the calculated cruising range more accurate. [0004] To achieve the above object, the technical sche...
